<p>#2018-08-10：<br>        开始记录开发过程遇到的错误，时间长了，遇到过解决过的问题也忘掉了，所以以后的问题记下来。<br>#2018-10-11：<br>        A页面和B页面都存在 一个WKWebView。 但是在实践中发现：localStorage信息不一致。在B页面使用localStorage保存信息。 回到A页面取不到相应的数据。问题在于每个WKWebView的 ProcessPool，描述是：The process pool from which to obtain the view’s Web Content process.<br>####解决方法：<br>把config中的processPool变为单例共享</p>
